lle it known that l, l nno llrous, a subject of the King; ol FBngland residing at lleices ter, lieicestel'sliire, llngland, havcinvented certain llnproremeuts in Pulling-(l ver lilachiues, of which the following description, in comic; tion with the accompanying drawine's is a. speciricatiom like relierenre charail-tors on the drawings indicating like ports in the several figures.

This iur-rentimi relates to macl'iines for use in the manufacture ol boots and shoes for pulling uppersover lasts.

in the pulling-over operation on boots and shoes it is necessary that the operator observe critically the cruulition oi the upper over the top of the :l orepart in order to de termine 'whetlulr any adjustment is requireifl to position the tip line oil the upper at the correct distance hour the end of the last and in the correct angular relation to the hmgitudinal median line of "he last and to the plane of the last bottom. ill-curacy of judgment in these r spects requires that the operator View the work with substantially the some perspective that the wearer of the 1 for 4'- mple, would here in viewing it upon his foot. ln order that this and other oiazrations may be performed with as little conscious eliort and fatigue as possible, it is iii. irahlo that the work be so positioned to all ord the operator a satisfactory criti cal View of the 'l orepart oi the upper without requiring him to assume any lllllliltlllltl or strained ilositioiu and that he he enabled to present the work to the machine andto perform any operations having to do with ttljllElilllOlll] oi? the upper or with control of the mzu-hine without the necessity for any material change in his VlGKVQOlHt with rel crence to the work. Notwithstanding; this prior pulling-over machines 'l'or milling the upper hy power--operatesl means have been so cmistructed and organised as not to allord the most satislaotrny position "for the work within. the ahorc-mentioned requirements. Prlwer-operated means for pulling the upper are, oi vourse, highly desirable.

The present invention provides a novel msranizatiou in whirh the shoe positioning and the power-o )erati'ur means "for a; r upping and other parts of the pulling-over machine, are so organized and combined as to produce a poweroperated pulling-over machine in which the work is positioned in the desired manner above outlinee. In the construction shown poweropcrated upper pulling means and means lior positioning the last and shoe are so constructed and arranged as to locate the plane of the tip seam oi. the upper substantially along a line of vision of the operator directed forvardly and downwariilly toward the work, and the parts of the machine which the operator is requirei'l to manipulate are so constructed and arranged as to necessitate no rhange in the position of the operator such to allert materially his critical Vl6\V oil the work. In the illustrative machine the shoe is inclined upwardly and rearwardly at an angle of substantially 50 degrees to the horizontal and is positioned somewhat below the level of the operators eyes. The invention, however, is not limited to a. construction in which the work is positioned at the precise angle and elevation illustratmh and it is to be understood that in hereinafter referring to the last or the shoe as positioned with. its toe end pointing in a direction ofnon-intersection with a vertical plane extending between the last and the operators working position it is intended to define a location of the work in which there is nosubstantial forward inclination oi? the last or shoe such that its forepart tipped toward the operator, irrespective of whether the last or shoe may or ma not be tipped more or less rearwardly away from the operator.

The invention is herein illustrated as embodied in a construction including many features oi a well-known type of pullingover machine; such as exemplified in prior United Fltates Letters Patent No. 663,777 granted. on December 11, 1900, upon an application of R. F. McFcely, and in other subsequent patents including Patent No. 1,029.38? granted on June 11, 1912, upon application of R. F. McFeely, to which reference may he made for an understand ing of details of construction not here'- inalte specifically described. lVhile the invention presents various noyel 'leatures of particular utility as embodied in this gen that in many of its aspects the invention is not limited to machines of this type.

The above and other features of the invention, including certain details of construction and combinations of parts, Wlll now be described with reference to the accompanying drawings and pointed out in the claims.

In order that the invention may be more fully understood, in its relation to the type of machine shown in the prior patents here.-

inbefore referred to, the reference characters of the prior Patent No; 663,77? and in certain instances also of Patent No.

1 09 9 387 will be used herein where conven- V 7 7 7 ient to indicate corresponding'parts.

I The operative parts of the machine are. 1 supported upon a frame comprising front and rear plates 2 and 4; respectively, connected by stay rods 6. Bolted to the. front" frame plate 2 and suitably supported at the "top of the rear plate 1 is the head portion 8 of the machine upon which are mounted the various instrumentalities for operating;

upon the upper and the last, and operating means for such instrumentalities comprising a cam shaft D which inthe present con struction is supported vertically with its driving pulley 986 in a horizontal position between the frame plates. The operation of thema'chine is controlled by a treadle X connected to one end of a lever X to the other end of which is pivoted a short rod X which serves in manner disclosed in said prior patents, upon the operation of the treadle, to actuate automatic means for retracting a brake'shoe 982 from the pulley 986, such means acting through a rod X and a lever X to operate a rod 984 whereby the clutch (not shown) is actuated to cause the pulley 986 to be driven by means of a suitable belt toeffect the first half of the cycle of operations of the machine,after which the clutch is automatically disconnected and the brake applied through the connections above described by such means as are fully disclosed in prior Patent N 0.. 663,777.

When the work is in position in the machine the last, with the upper positioned loosely upon it, is supported, as indicated by dotted lines in Fig. l, with the rear portion of the upper on the last in engagement with: a heel rest 10 and with the forepart of the insole 011 the lastpo'sitioned upon a sole rest 12. In this position the upper is engaged by the usual frontfand'side grippers, of which the front or toe gripper is seen at 14: in F 1, and is pulled over the last automatically during the first half of the cycle of operations of the machine above referred to. The front gripper is connected to an updrawv lever e which is pivoted on rod 152:

.and has connection at its rear end through its springs 1 16:, and rods 136 to a cam slide 13 1..

uring the second half of the cycle of operations, which takes place upon a second depression of the treadle X, the margin of the upper is carried inwardly under the bot-- tom of the last and,.following movement of driver bar arms 61 2, 6742 and 676 inwardl under the last bottom, the fasteners are inserted to retain" the upper in its pulled-over position. lVhilethe machine isat rest between the two portions of the cycle of opera tions, the operator is afforded opportunity to change the tension under which the upper is .held orrto effect such adjustment of the upper on the last as may be necessary in order to correct any inaccuracy in its position through the manipulation of various intense instrumentalities of which it is only neces sary herein to refer to handles 158 which con'iprise upwardly and forwardly curved extensions or the side gripper levers i, and a handle 0 comprising a similar extension of the front gripper operating lever c, whcrcl y the operator is enabled to manipulate the different grippers as desired. Pivotrd on thrhandle c a lever 1226 con nectcd by a link 2% to the usual lever 226, whereljiy the opening of the front gripper may be effected.

The work positioning means and the operating instriunentalities hercinbefore de- S(.'lll)tlll are so arranged in accordance with the illustrated embodiment of this invention that the heel end of the last is supported substantially over the front frame plate 2 of the machine and the last is inclined upwardly from its heel end toward the rear of the machine at such an angle that the operator, as he maintains a natural attitude at the front of the machine, may, without special effort and without bending over, look downw rdly and forwardly upon the top and sides of the fore'pa-rt and substantially along the plane of the tip seam of the upper on the last and lrecp the work continuously in VlOW in this manner until the operations are completed. The various instrumentalities whereby adjustment of the upper may be effected, romprisinp; particularly the handies L58 and c together with the lever 226", are, moreover, arranged in such relation to the work and to the position of the openator that he may manipulate them without the necessity of changing materially his viewpoint with reference to the work and without in any way obstructing his View of the work. in order to insure these results the handles referred to are preferably extended, as shown, to positions somewhat higher than the wort: and far enough forwardly to permit the operator to manipulate them without stooping. in the crmstruction shown the last is positioned at an inrline of substantially :0 degrees to the horizontal, this angle having been determined as particularly satisfactory for the objects in View under average working conditions, but it should be understood that the invention is not limited to a construction in which the last is positioned at the precise angle shown. will be observed by reference to Fig. l

that the perative portions of the marhine are substantially at the rear of a vertical projection of the treadle X, and by reason of this arrangement the operator may maintain a single position close to the work both for operating the trcadle and for manipulating the upper and the last.

The construction shown is particularly ZillttPtO-(l for driving fasteners in the form of ta: its, as is usual in machines of this type. For, asserting and arranging the tacks the machine shown includes a tack pot dill) of any usual form and raceways in, equal in number to thenumber of tacks to be driven at each operation, upon which the techs hang suspemled in rows by their heads. The

tan-l: ot an, in the construction shmvn, is supp upon a bracket 18 and is rotated in the usual way from the cam shaft l) 1 its 553 iig. as heretofore constructed. 1 he tacit, as thus supported, is moved into inement with an opening 28 in the bracket plate 31') wl ch serves to support the rare ways. Communicatiiu; with this opening, at its lower end is pipe 32 which leads to a vaivi 53% arrangeril to control the admission to the pipe 32 of compressed air from a supply pipe 36 which may communicate with an air pump or with any suitable supply of ir under pressure. The construction shown romprises a single pipe 2:32 leading; to the several 01 innings 28, but it will be understood that several conduits 2-32- may be arranged to communicate with the several openings Positioned over the if desired. separators 9.4 is a bar 38 provided with openings it) which are over-the heads of the respective tacks after the latter have been moved by the members 2a to separated position. Associated with each of the openings til is a block i2 pivoted to the bar 38 and having an opening M; arranged to aline with the opening 443 when the block i2 is in the position shown in Fig. 7 and in full lines in his. 8. laceway covers t6 rest upon the blocks 4-2, and upoi the lifting of any one of these covers the corresponding block may be swung asid 1., as indicated by dotted lines in Fig. 8, in order to permit the raceway to be cleared in Jase a tack becomes wedged therein.

Ehipported at one end in the bar 38 and communi:'ating with the respective openings 40 are curved conduits 48 which lead to various points of delivery or presentation for the tacks to permit them to be supplied to the diff "ent tack inserting instrumentalities. The conduits id are, it will be understood, equal in number to the number of tacks to be driven at each operation and are grouped and arranged as reference to the particular points at which the fasteners are to be driven in the work, the delivery ends of these conduits being supported on brackets 50 on the machine frame. ll ith this constrru'tion and arrangement, a blast of compressed air from the required with v plates 2% pipe 32 will lift the tacks from the separator and force them into and through the respective conduits l8 to their points of delivery, the curved form of the conduits 4i causii' "11 ed in such manner as to be finally (01118 invei n'esented point upward.

The driver bar arms 672, 67 i and 676 have their usual movement toward and from driving positions with respert to the margin the last bottom. Vfith reference to Figs. :nd 10, the driver bar 676, which is one of the side arms having means for driving two tacks simultaneously in the side margin oi' the last bottom, is arranged for movement toward the left into position to drive the tacks and toward the right away from the last to itsinoperative position, the arm being shown in these figures as in position to permit the tacks to be driven. it will be noted that the delivery ends of the corresponding ronduits 48 are positioned adjacent to the path of movement of the driver bar arm, and the machine is provided with ontrolled by the movement of the .3 eiiecting a transfer oi. the tacks rem delivery position into position to be driven. The construction shown for effecti. g this transfer comprises a plate 52 pivoted at 54.- on the upper end of the driver bar arm, the plate having tack pockets oo normally closed at their lower ends by a spring pressed gate 58 provided with a sloping face arranged to be engaged by the endsoi the drivers-(31d in their driving movement to cause the plate so tobe pushed aside and permit the drivers to enter the tack pockets and expel the tacks therefrom. The is provided with a tail portion 62 ha. ng surfaces 64C and 66 arranged to engage a stud '68 on the bracket to control the positions indicated in Figs. 9 and 10 the surtace (id is in engagement with the stud (i8 and the plate 52 is positioned in such relation to the drivers 614: and the tack block that'the tacks are supported point upward in the pockets 56 andare in position tobe driven upon the operative movement of the drivers. W hen the driver bar armis moved 7 to its inoperative position, which is toward the right in Figs. '9 and 10, the stud 68, in cooperation with the suria 0e 66, permits the plate 52 to be swung by the spring 70 about the axis 5-4 to the dotted line position (Fig. 10), in'which the pockets 56 are in line with the delivery. ends of the conduits l8. lVhile the transfer plate is in this position tacks are forced through the conduits 48 and deposited, point upward,in the pockets 5 6 inthe manner hereinbefore described.

e tacks in taeir passage to be of the arms has similar mechanism associ ated therewith. V v

p In order to control the admission of compressed air to the conduit 32, the valve 3- is connected to a short shaft 72 upon which is secured a hub Tet provided with diametrically opposite ratchet teeth 76. Mounted loosely on the shaft 72 is anal-m 78 provided with a spring pressed pawl 80, the arm 78 being rigid with a pinion 82 which is ar ranged to be turned in opposite directions alternately by the movement of a rack bar The bar 892 is arranged to be moved toward the right (Fig. 1) during the pulling movement of the grippers in the first half of the cycle of operations oi. the ma chine through connection of the bar with one of the side lever updraw rods 136 by means or an arm 86 which bears at its outer end upon a collar. on the bar Set. During this movement, whereby the pawl is turned about the hub 74 to cause it to engage the diametrically opposite tooth without operating the valve 34, a spring 90 on the bar S i is compressed and a dog 92 on the bar 84- is caused to engage a spring catch 94-, whereby the rack bar is retained in the position'to. which it is moved. In the latter part of the second half of the cycle of operations oi? themachine the return of the arm 86 as the grippers are returned to starting position causes a trip 96 on the arm to engage the iiatch 94- and withdraw it from the dog 92 in such manner as to permit the spring '90 to force the rackbar toward the left and etfect an opening and closing movement of the valve 34;, movement of the rack bar in this direction being retarded by means of a dash pot 98. In this manner the tacks are caused to be delivered pneumatically to the trans terring devices at a time when these devices 7' are positioned to receive them while the driver .bar arms are in their retracted position. 7 V

In the use of the'inachine the operator stands close to the front frame plate 2 in po-' sition to operate the treadle X The work, positioned within easy reach of the.

operator, as indicated in dotted lines in Fig. 1, is below the level of the operators eyes and is inclined at such an angle as to afford the operator a full and critical view of the top of the upper and the portions around the sides of the forepart of the last without any special effort upon his part such as would finally cause fatigue. The various handles which frequently require manipulation or the purpose of adjusting the upper, including the handles 158 and 0. are so arranged as to be w1th1n easy reach of the operator as he stands in the position described without involving any obstructlon oi his view of the lessees work. Upon the first depression of the ii the l. li?( oi the grippers, u? on the some time racl bur lilis retrzjecnzul in preparation 1 the subsequent operation of the Vela-e Oi: the driver our arms at this time being tru d i l' the pockets oi the; transfer pistes: m8 ui line with the duits it; from which they have rece L rerted tacks in a previous operation oi the macl-iine. Upon a subsequent depre sion of the tl'ililtilhl, utter the necessary ad i nent oi? the upper on the lust has been ell'ected, the margin of the upper is carried inwardly under the lust bottom, the driver bur urms move inward causing the plates 59. to swing; shout their pivots and curry c tacks into elinement with the drivers, and through the operation elf the drivers the techs are inserted to fasten the upper to the sole or innersole (herein termedgeneri eliy the sole). The driver bur arms then swing oi'itwurdly and cause the pockets 56 again toaline with the conduits s8, and substantially simultanemisly, es the grippers ore returned to starting position, the valve is operated in the manner described to cause the sever-all tacks under the con ol o the separator 14-. to be forced through the conduits 4:8 and deposited point upward in the pockets 56 which. arrive in al nement with the conduits in time to receive the tacks. 4
